thanks for your comment 1st of all

so you will waste 2 summ.spells(exhaust and ignite)in order to boost your early game?
and what if the enemies have seen your 2 aggressive spells and overextend/be aggressive
then your perfect plan went bye bye.

about the mana regen masteries,it stayed from my 1st build, and i intended to change them only for the second 1.

lets just say that 1st build is more defensive and stable and the 2nd one more aggressive and a faster trinity

Honestly I like the build, but I rather make my masteries 22-0-8.
And I know mana could be usefull, but I never waste time making a mana item with so low dmg. But I dont aprove 9-0-21 system, unless u r going Hybrid/Magic.

And with my personal build I can always FB mid and make diference sinec early game opsite from this build.

Sheen is a must have on all ezreals the 1st Ez Option on making a Drop, I get the poit but, u will lose a lot kills, having a lot of enemys runing away with a miserable 1HP-15HP.

Has for life steal, well u really can make a diference wen you have 2 Bloodthirster and a nice atk-speed. But early game, dunno, but yeah might come handy...

PS: EZREAL is one of the best characters in game wen it comes to EARLY GAME, you should take more advantage of that. Specaily with EXAUST + IGNITE you can even kill a UDYR Tank+Baron and even tryndamere if u play it wright.

i only start building manamune from early so that as i farm its passive will stack.if i don't start building it at early game then late game i will only have the item not the fully stacked version of it

i got essence flux at level 4 only for one reason:if there is a jungler at the enemy team then it is most likely to be an attack speed/attack damage,and if i get silenced/stunned and cant use arcane shift,then my only other option is to lower his attack speed.

but than that, u have a point regarding the a quints,the only reason i chose them is because my physical damage rune page was identical to this one,and it really worked great with me

finally,u really have a point about exhaust,its just imo,great 1v1s or pinning down a serious thread of the enemy team for 3 sec or so

but other than than thanks a lot for your constructive criticism

You shouldn't even get essence flux at level 4, its damage is nothing and its only use is in late game to boost your teammates.

As for runes, i would switch out the AS quints for flat AD. In lane to farm you should be just last hitting, which you don't need attack speed for. AD would make it easier to last hit than AS.

Secondly manamune destroys ezreal's mid game. Its a great item for late game, but mid game(which is ezreals strongest point) you lose so much damage because of it(since you still won't have that much mana). IMO a bloodthirster would be so much better.

Lastly i would switch exhaust into the "what you could" section. In lane you can dominate anybody at lvl 2 with it. Not to mention it can also be used defensively. For instance, if a xin zhao dashes to you and you exhaust him, he's not gonna be able to do anything.And you might want to last whisperer into optional items, since you won't be able to do much to high armor opponents without it even with black cleaver.

I'm not going to vote down, because i like the written guide and parts of your build, but these things are dragging it down.
